QDialog out of a console application

I have a QCoreApplication console application. When this application runs into an assert, I would like to have a QDialog on my screen with a few radio buttons that give me a choice how to continue from here.
Of course a console application will not let me create a QWidget, let alone a QDialog.
Anybody out there who once had the same problem and knows of a smart way to solve it?

Thx
